[Qgis-psc] QGIS 2.16 sponsored bugfixing report

[Sandro Santilli]

I've completed my budget hours (and actually spent 13 more) on
a few old critical bugs found on hub. The full list is on the
google document [1], but here's a list of the most important ones:

 - PostgreSQL support for primary key with negative values (#14262)
 - Crash on undo in composer (#11371)
 - Inability to select invalid polygons (#13635)
 - Node tool snapping to random geometries (#13952)

The bugfixes were backported to 2.14 where appropriate and tests were
added when possible.

Once again writing the tests was a big cost, so much that I finally
had to give up on the test for #13952 (node tool), having been over
time for more than I could support.

I hope a new round of testsuite-only activity will be funded sometime
in the future to make it easier for developers to secure fixes, and maybe
then make it mandatory for a test to come with each fix.

Thanks again for the opportunity !
